1:The control flow of the program;

2: When we set the MAXPRIMES less than 5 but greater than 2, than the use case 5 would find the fault that the array is out of its boundary, while the use case 3 would not.

3: When we input n equals 1, since the numPrimes has already been one, the while loop will not be executed, but the program will go to the for loop directly.

4:

NC: TR={1,2,3,4,5,6,7,8,9,10,11,12,13};

EC: TR={(1,2),(2,3),(2,10),(3,4),(4,5),(4,8),(5,6),(5,7),(6,8),(7,4),(8,2),(8,9),(9,2),(10,11),(11,12),(11,13),(12,11)};
